Rather than training soldiers for combat, the Portal beams them in from space. It is a large blue sphere, suspended in the air beneath a structure that resembles a giant, warped football goal. The length of time and cost of teleportation varies between different Scrin units, depending on their complexity - simple groups of Buzzers take almost no time at all, while the Mastermind takes considerably longer. Once a Portal has been established planetside, a Stasis Chamber may be warped in to allow access to advanced infantry: Shock Troopers, Ravagers which also require a Nerve Center, and the Mastermind or Prodigy which require a Technology Assembler as well. From the get-go, however, Scrin Foremen are free to call down Buzzers, Disintegrators and Assimilators as funds permit.
